HINGE-DOOR.

Specification of Letters Patent.

Patented Jan. 13, 1914.

Application filed November 11, 1911. Serial No. 659,868.

To all whom it may concern:

Be it known that 'I, CHRISTOPHER J. LAW- LESS, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Hinge-Door, of which the following is a specification.

The object of the present invention is to provide a door for silos, which may be readily swung into an open position, a further object of the invention being to provide a hinge member of novel and improved form. adapted to serve, at the same time, as a portion of a ladder, whereby the silo may be ascended.

A further object of the invention is to provide novel means whereby the door of the silo may be trued-up, and to provide means whereby the door may be elevated and lowered, so that it will fit properly in the doorway of the silo.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construct-ion hereinafter described and claimed, in being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying draw ngs, Figure 1 shows in elevation, a portion of a silo equipped with the door of my invention; the latch mechanism being in locked position; Fig. 2 is a similar view showing the latch mechanism in unlocked position; Fig. 3 is a perspective of the hinge member whereby the door is assembled with the silo; Fig. 4 is a transverse section of one of the door-carried bearings in which the intermediate portion of the hinge member is journaled; and Fig. 5 is a plan of one of the bearings.

In the accompanying drawings, a portion of a silo is shown, the same being denoted generally by the numeral 1, the silo, obviously, constituting the supporting structure upon which the door 2 is mounted. The door 2 may be equipped with transverse reinforcing bars 3.

The hinge member, as clearly shown in Fig. 3, comprises an intermediate portion 4 and rectangularly disposed arms 5, terminating in fingers 6, which are disposed substantially parallel to the intermediate portion 4 of the hinge member. Moreover, as shown at 7, the arms 5 are spaced from the plane in which the fingers 6 and the intermediate portion 4 are located. Likewise, as shown at 8, the central portions of the arms 5 are depressed, for a purpose to be described hereinafter.

The fingers 6 are pivotally received within sockets 9, which are secured to the silo 1. The intermediate portion 4 of the hinge member extends longitudinally of the door 2. Upper and lower bearings are mounted upon the reinforcing bars 3, and in these bearings, the intermediate portion 4 of the arched hinge member is ournaled.

The bearings, as clearly shown in Fig. 4c, are two-part structures, these parts consist-- ing of base plates 11, from which flanges 12 project, the flanges 12 terminating in coiip crating parts 1 1, in whichthe intermediate portion 1 of the hinge member is immediately journaled. The flanges 12 may be detachably united by means of bolt and nut structures 15. In the base plates 11 there are cruciform slots 16, parts of which extend substantially parallel to the intermediate portion 4 of the arched hinge member. Connecting elements, preferably taking the form of bolt and nut structures 17, are adjustably mounted in the openings 16, the bolt and nut structures 17 being connected with the reinforcing bars 3 of the door 2.

Mounted upon a suitable part of the portion 4: of the arched hinge member, are washers 18. Should it be desired to elevate the door, these washers 18, certain of which are temporarily disposed above the lower bearing, may be placed, one at a time, beneath the lower bearing, thus elevating the door. Owing to the fact that the bearings comprise separable parts, detachably united, as shown in Fig. 41, by merely removing one of the bolt and nut structures 17 and the corresponding bolt and nut structure 15, one or more of the washers 18 maybe slid in the plane below the lower bearing, thus providing for an elevation of the door.

Should the door lose its true rectangular form, the door may readily be trued up, owing to the adjustable attachment between the bearings and the door, as atforded by the mounting of the bolt and nut structures 17 in the cruciform slots 16 of the base plates 11 of the bearings. The horizontal branches of the slots 16 permit the door 2 to be adjusted horizontally to fit in the door way.

Owing to the fact that the arms 5 are of the parts 5 from the door, as shown at 7,.

permits the door to be swung inwardly, the hinge member fitting closely around the edge of the door-way, adjacent the sockets 7, the door-way being impeded, therefore, to the smallest possible extent, the sockets 9 and the fingers 6, alone, serving to encumber the door-way, when the door is in open position.

Any desired form of latch mechanism may be applied tolthe door 2. In the present instance, a bar 20 is applied transversely to the door, and upon the bar 20 are pivoted, intermediate their ends, as shown at 21, a pair of latch members 22, terminating at one end in angularly disposed bills 23, each latch terminating adjacent its opposite end in an operating handle 24. The operating handles 24 are pivotally connected by a tie bar 25. Secured to the stiles of the silo door-way, are striking members 26, behind which the bills 23 of the latches are adapted to engage, it being obvious that both latches may be manipulated simultaneously, by swinging the handle portion 24 of either latch. The handle portions 24 of the latches are spaced, by the bar 20, from the door-proper 2, so that the handles 24 may readily be seized, to swing the latches.

Owing to the fact that the hinge member is of one-piece construction, as clearly shown in Fig. 3, a sagging of the door will be pre vented to a large extent, the form of the hinge member serving to make it unusually rigid.

Having thus described the invention, what is claimed is 1. In a device of the class described, a frame; an arched hanger; means for pivotally connecting the ends 'of the hanger to the frame "a door. across which the intermediate portion of the hanger extends; a bearing on the door engaging the intermediate portion of the hanger and independent of the connecting means; and mechanism independent of the hanger for connecting the bearing to the door for movement transversely of the intermediate portion of the hanger.

2. In a device of the class described, a frame; an arched hanger including arms and an intermediate portion; means for pivotally connecting the arms with the frame; 65. a door across which the intermediate portion of the hanger extends; a bearing on" the door engaging the intermediate portion of the hanger and independent of the connecting means, the bearing being spaced at one end from one arm to permit the bearing and the door to be moved longitudinally of the intermediate portion of the hanger; mechanism independent of the hanger for connecting the bearing to the door for movement transversely of the intermediate portion of the hanger.

3. In a device of the class described, a frame; an arched hanger including arms and an intermediate portion; means for pivotally connecting the arms with the frame; a door across which the intermediate portion of the hanger extends; a bearing on the door engaging the intermediate portion of the hanger and independent of the connecting means, the bearing being spaced at one end from one arm to permit the bearing and the door to be moved longitudinally of the intermediate portion of the hanger; mechanism independent of the hanger for connecting the bearing to the door for movement transversely of the intermediate portion of the hanger; and movable means on the intermediate portion of the hanger for supporting the bearing and the door in adjusted positions longitudinally of the intermediate portion of the hanger.

5. In a device of the class described, a, frame; an arched hanger having its ends pivoted to the frame; and a door pivoted 115 to the intermediate portion of the hanger and adjustable along the intermediate portion of the hanger in the direction of the length of the intermediate portion of the hanger.
